One of my friends have been facing an issue with QImageLable - the trouble is that when he does not specify the CacheFolder for the lable, the image rendering fails. The reason specified in the error log is - 'filename too long'. Is there somehow we can fix this? The error log says this:

[Wed Feb 27 12:26:29 2013] [error] [client 127.0.0.1] (36)File name too long: access to /eNp9Vsly4zYQnU9J8ZhDJEqWF_okyXasZCxrLI2dnFIg2aQQgwAHAL1Nzb-nAQIgKXtycZXxen39uqnbJI6T6MuqIiV8JimwKDk5Sb6rJD5Jok-_flJaLkm2hyvBcpDR-focoZmHroSEpWACAZUcJ1FRZBkh0cBmQbLHvs10Gsenp9bmqIvD9Za-QXROk4lBxh7ZwYu2tljlNTAmfnkQkuX2qa2Qcv3XUgiZU060jTAegH-_ByctmDJuiiulaHi-k4SrmkjgmC9tY4QeLD271xpM3mkS1by0FUx9ki8NYVS_mgTx2Poe-xTbSgi9Nx2auLFJH_u410LSN0QImzNachMTOWFQtD2febt7kJpmPStMrEVtjU59DRuSY5vlA8313hbShejQa6DlXgc49vC2JllH3sw_74w1B6UCFDzmvGQdo7OBWnJL2BVlsCGmmPV5X1ALnAdIp4mPoK1-ZeDkshZ6Czr6wMo1uh4oaanUkhFT77obEE7hgqqakVc_AscaOjjgJymPvL-Z30IY4TltHPeRFU6QZu91Y7A1qUCZYDMsZqTk0-j5-XmUNSnkI8oz1uSgRt_a___JcKFGBXqp0e-oGpr9Vhdpb8wu3-0TSEY5hIxnfXSrJX0E0eiP4a88P_AOMr5FFVgZD9d8nmUogT_BAZOJBSr6siSNAnWPzedEU8FDxEmYRyNVWP0esWEwl5ykDPIwmMD4HXxrqISO8aMgSpKusIeXoMlpuBZCsB2tXZlhzboCL6UMogsl3FNFUwZhPY-930ZCAVjCHRjKbkDvRe5aaZ-iQa9-t9bdnuBrX6Yh8rWu2AIKnPYh1waZFzrc2iDUFcc_TWa6GKrb5CCSU3OThstgZFIw8fwzXZsWhaLt5A5MzjpOHZ_dUf5sD1SvbpH-

What can be the solution? I am stuck because unless you bring in the database again (and I don't want to bring that in) for this control, it may not be reliable. Otherwise, we have to make the 'CacheFolder' mandatory.

The issue #92 can be related to this.

Probably not. I guess what we are doing is to serialize/deserialize the
control and it is getting too long!

Compression/Decompression is working fine. Also, I am not able to reproduce
#92 on my end either.

The link where the problem is described: http://serverfault.com/questions/388858/how-to-fix-file-name-too-long-error-in-apache2

It seems that in a case of CacheFolder not set, the whole QImageControl architecture is broken. It can produce URL's that would be rejected by the web server. The QImageControl should be redesigned.

Yet another instance: http://www.c-integration.com/forum/showthread.php/50-qimagelabel-not-working

How about we make CacheFolder a mandatory property (which when not set will raise a red flag)?

The QImageControl and QImageLabel are forced to have a limit of 255 f…

…or file name length.

* It fixes issues qcubed#92 and qcubed#152
* The example of QImageLabel is changed to use CacheFolder property.
* The exception is throwed if the CacheFolder is not specified and the resulting file name length exceeds the 255 limit.

The resolution proposed here: bug-152. Waits for the #188 to be accepted.
